I just noticed that in every pizza there's an item when pressed for double and then pressed another standard item as half, it would charge an extra item until you press a third item as half then it reduces the charge to normal.It will be easier to explain if you go to our online order at aromapizzeria.com and order a large house special double bacon half no mushroom, you'll find yourself charged 2 extra toppings instead of just one half.It's weird that this is the case with every pizza but different toppings.I tried things like creating a new pizza, and changing settings for the item but no luck, I don't know if it has always been like that.
